I don't see a topic on here that digs into this subject thoroughly, so I thought I'd start one. I'm not as interested in the technical explanation of the buzz (which I've been reading about) but rather, what kinds of actions YOU can take, or accessories YOU can use, that will cause vs. not cause the interference sound?
I found a few audio clips to help you know if it's what you're hearing:
Steady version:

Staccato version (over music):
http://www-sigproc.eng.cam.ac.uk/~hl309/DAFX2006/5_pop_noisy.wav
And other beats of that same pitch are also common.
One question, specifically for cars (where you don't always choose your own speaker system): if your iPhone accessory is iPhone-ready and doesn't trigger the Airplane Mode warning, are you still at risk of your car ITSELF picking up the interference?
I get the buzz sometimes with my iTrip Autopilot (3G-ready 4046-TRPAUTOC) and Griffin's support has been helpful so far (mine gave the Airplane warning at first and may need to be swapped). But I don't want to blame the accessory if, in fact, my car will ALWAYS pick up the buzz no matter what's connected to the phone.
And beyond just cars--aside from accessories made for iPhone specifically, are there any guidelines for what kinds of devices/speakers will or will not have the problem? I never hear it with any headphones, for instance, nor do my Macs' internal speakers seem to pick it up.
Also, how close does a phone have to be to make interference likely? Could it come from a neighboring home or another car, or is your own phone really the only likely culprit? (In my case I've heard it when alone on a country road.)
And does it matter whether you are on EDGE or 3G? (Doesn't seem to matter in my case.)
Any other advice/tips on troubleshooting or avoiding this?
I'll start things off with a DIY project I found that can shield any speakers--if you can access the wiring and have some old USB cables around:

(Feel free to merge if such a topic exists, but I couldn't find one.)
